Hi, I bought a used a 2001 XJ8 with no owners manual. And need to know how many quarts of oil does this year/model uses? And what weight of oil does the manual specify? Or what would be the best weight of oil for Dallas, TX? (it gets real hot here in the summer up to 105 degrees; coldest in winter around 30 degrees. However if I did drive the car around the country would there be a better all around weight of oil to use (for all conditions)?

Hello....simple answers ;o)
Capacity around six quarts (6 litres)
Summer temps use a good quality full synthetic 10W50
Winter temps use " " " " " " 5W40
Hard driving in hot conditions you would be better to stick with the 10W50
lesser grade oils just don't cut it when temps heat up.

Your recommendations contradict those of Jaguar in terms of quantity, type and viscosity. What experience do you have that indicates that they got it wrong?
For a 2001 AJ27 used in an X308, the 2004 specification booklet specifies
API SJ/ILSAC GF-2 or API SL/ILSAC GF3. There is no viscosity specification.
Further down in the fine print, the booklet has some viscosity recommendations. The
vehicle care booklet also shows that viscosity range selection is subject to climate
considerations.
There is a capacity change at the 2000 model year. 6.4 US quarts versus 7.4 US quarts for
non-cooler applications. This is mainly due to a change in specification rather than a
physical change in the pan as noted in the "silverstone" oil level thread. All they did was
ship a different dipstick with different markings. There is a TSB about this and the
change in dipstick part numbers.
That must be a "refill" capacity because the vehicle care manual excerpt above
for a 2001 XJ shows 7.9 US quarts for a non-cooler XJ. The difference may
be that this is a "dry" capacity which would never be encountered during
a routine oil change.
Personally, on a XJR with cooler, I fill from large bulk containers of Shell Rotella 15W40
and it takes just about 10 US quarts to do the dirty deed since I choose to run the
"silverstone" fill specification. It is intended to overcome oil starvation in hard
cornering.
That does not agree with the specification booklet at all because it calls for
7.4 US quarts with cooler. So who knows.
Everyone drains the pan differently, so the best guide is the dipstick.
Treat the "spec" as being only for shopping purposes to avoid being
short on the refill.
Shell Rotella 15W40 would be a great choice for a Dallas based car.
Thanks very much, all of you are very helpful. Bye the way, What is the best or one of the best radiator Coolants to keep on hand if ever needed to top up? And would anyone know what the hex nut cap not far behind the radiator fan in the middle of the engine bay, what it's use for; just curious?
Jim or others whats your opinion on "What is the best or one of the best radiator Coolants to keep on hand if ever needed to top up? And would anyone know what the hex nut cap not far behind the radiator fan in the middle of the engine bay, what it's use for; just curious?"
(I think you answered my original post before I edited to last questions. (I hadn't use the scroll bar on my browser to see that 3 was actually showing the radiator cap if you scrolled to the right)
Had my fair share of coolant leaks and subsequent repairs. Always used Prestone Dextrol 50/50, orange color, to either refill system or top off. Always a jug in the trunk !
I had a hose pop off last Winter when it was exceptionally cold here. I shut it down, went in to the Doctor's office for some shots in the knees. When I came out, it had cooled. I had enough coolant left in the radiator and engine to get me to a gas station before the thermostat opened: since then I have always carried 50/50 orange colored coolant with a funnel in the boot just in case . . . along with a long bladed screwdriver. When cars get old, strange things happen, but there is Boy Scout motto to cover most contingencies.

Here is a JPEG showing the XJ8 ZF5HP24 transmission diagram (shows drain and fill plug):
The 1998 to 2003 XJR has mercedes WA780 transmission (that has a plugged dip stick tube that allows the plug to be removed and and drip stick inserted).
Good answers, but nobody addressed" And would anyone know what the hex nut cap not far behind the radiator fan in the middle of the engine bay, what it's use for; just curious?" by Ben.
I would suppose that is used for bleeding air from system. looks like the high point in the system.
Yes, that hex nut is to bleed the cooling system. It is the high point. If you still have a plastic one, it will eventually leak. A replacement aluminum thermostat housing will give you peace of mind.
